Create a surface between two sets of boundary curves

You can build a blend between two boundaries defined by sets of surface curves. For example, you can use this tool to create a surface that forms a smooth juncture between a creature’s arm and torso.

1. Select Edit NURBS > Surface Fillet > Fillet Blend Tool.
2. Click the surface curves that form the first boundary, then press . You can use isoparms, edges, or curves-on-surface.
3. Click the surface curves that form the second boundary, then press .
   

   If you edit the surfaces that provided the input curves for the blend, the blend updates automatically.

   Note:

   If you use the manipulator handles to adjust a fillet blend between straight lines (such as the edges of two planes), twisting and unexpected results may occur.

Troubleshooting a fillet blend surface

If the resulting fillet blend surface is twisted, you can try the following:

• Reverse the direction of the surface curves at one end of the blend.
• If reversing the curves is undesirable, use the Reverse Direction Left/Right attribute to reverse the surface after it is created.
